Abstract (en)
A cadmium electrode for use in rechargeable alkaline cells is disclosed featuring use of dispersed polyamide having specific properties. The polyamide serves as a binder as well as an anti-agglomerant to retard cadmium agglomeration during use of the electrode. The use of elemental silver additive dispersed throughout the electrode is also disclosed, as is the use of zirconium material as an electrolyte wicking and anti-compressive agent. A process for making any of the foregoing electrodes is disclosed featuring the step of forming a paste by mixing together the polymeric resin, active cadmium material and a non-aqueous solvent, applying the paste to a conductive substrate and removing the solvent. Alternatively, known prefabricated cadmium electrodes, such as teflon-bonded or sintered types, are post-treated through dipping or the like in a solution of the aforementioned polyamide.
